Applying the principle of parsimony to the trait "ability to fly," which of the two phylogenetic trees is better? use the following information to answer the question. two phylogenetic trees. in tree one the main branch divides into two branches 2a and 2b. branch 2a leads to worm. branch 2b divides into two branches 3a and 3b. branch 3a leads to cow. branch 3b divides into two branches 4a and 4b. branch 4a leads to moth. branch 4b divides into two branches that lead to bat and bird, respectively. in tree two the main branch divides into two branches 2a and 2b. branch 2a leads to worm. branch 2b divides into two branches 3a and 3b. branch 3a leads to moth. branch 3b divides into two branches 4a and 4b. branch 4a divides into two branches that lead to cow and bat, respectively. branch 4b leads to bird. applying the principle of parsimony to the trait "ability to fly," which of the two phylogenetic trees is better?
(a)-tree 1
(b)-tree 2
(c)-both trees are equally parsimonious.
since the trees show different evolutionary relationships, you cannot determine which is more parsimonious.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
